Abstract

A method and system delivers microwave energy to a vessel, such as a vein for the treatment of varicose veins, in a controllable heating pattern and to provide relatively fast heating and ablation of the vessel. The method and system comprises a microwave delivery device for heating the vessel, and a microwave power source for supplying microwave power to the delivery device. The method and system may also include a cooling system, a temperature monitoring, feedback and control system, an ultrasound or other imaging device, and/or a device for assuring generally uniform energy delivery in the vessel.
